LOCK FOR BEARlNG-PlE CES OF JOURNAL-BOXES.

SPECIFICATION forming part of Letters Patent No. 731,694, dated June 23,1903. Application filed December 9, 1902. Ser al No. 134,515. (Nomodel.)

To all whom it may-concern:

Be it known that I, GEORGE W. LEWIS, a citizen of the United States,residing at Portsmouth, in the county of Norfolk and State ofVirginia,haveinvented a certain new and use ful Improvement in Looks forBearing-Pieces of Journal-Boxes, of which the following is a full,clear, and exact description.

The object of this invention is to provide a lock for holding in. placethe bearing for the journal within a journal-box in such manner that thesaid bearing may be accessible at all times for renewal or repair.

The invention consists of a j ournal-box providedwith a transversepocketnear its forward upper end in which is arranged a sliding boltcapable of being dropped down to intercept the wedge or key used to holdthe bearing or fbrass in place and also capableof being lifted up withinthe pocket, so as to clear said key or wedge and render it accessible.

. In the accompanying drawings, illustrating the invention, in theseveral figures of which like parts are similarly designated, Figure 1is a longitudinal section. Fig. 2 is a transverse section takensubstantially in the plane of the line A B, Fig. 1. Fig. 3 is a frontele- Fig. 4 is a perspective view of the bolt detached. 1

I have shown the invention applied to a journal-box having, among otherfeatures, a bottom constructed with an inverted-"V ridge, substantiallyas in the Patent No. 706,243, dated August 5, 1902, and, also havingarear wall in which. the ordinary dust-guard and its pocket arereplacedby a hollow projection adapted to be packed with waste and oil inaccordance with the invention of my application for patentfiled December9, 1902, Se-

rial No. 134,516, toexclude the dust; but of course I do notlimit theapplication of the invention to either form of box.

Upon the top. ofthe box and near its front is erected a pocket 1, openat each side of the box and opening at its bottom into the interior ofthe box and extending transversely of the box. Within this pocket isarranged a bolt 2, herein shown as having across-head 3 and a lockinghook or hill 4 at opposite ends, with a fastening device, such as acotter-pin 5,,in its hook end for holding it against accidentaldisplacement. This bolt is arranged rather loosely within the pocket andby gravity falls down into its lowermost position. In line with thepocket the side walls of the box are slotted, so that the bolt may falldown into the box a sufficient distance to project its width across theplane of the key or wedge 6, which is ordinarily used to hold in placethe brass or bearing-piece 7. As shown in Fig. 1 and in full lines inFigs. 2 and 3, this bolt interposes its width in front of the said keyor wedge, and consequently holds it in place, and, as indicated by thedotted lines in Fig. 2, said bolt may be lifted up into the pocket 1 outof the plane of the key or wedge, and thus expose the said key or wedgein such manner as to render itreadily accessible for removal whenevernecessary to renew or replace the bearing or brass.

The bolt is inserted in the pocketbook end foremost, and when soinserted the cross-head 3 retains the bolt in place at one side and thehook 4 and cotter-pin or other fastening device hold it at the otherside, so that in the manipulation of the bolt no portion of it has to beremoved or detached from the box, and thus danger of its loss isminimized. Thus is provided a very simple and etlicient lock without anyvery material addition to the weight or cost of the box.

What I claim is- 1. A journal-box, provided on its topand near its frontend with a transverse pocket open at its sides and bottom, and agravitybolt arranged in said pocket and adapted to drop into the planeof the key or wedge of the bearing, and capable of being retracted intothe pocket out of the plane of said key or wedge.

2. A journal-box, provided at its top and near its front end with atransverse pocket open at its sides, the sides of the box having slotscoincident with the said side-openings,

and said pocket opening into the boX, cornmy hand this 6th day ofDecember, A. D. bined with a gravity-bolt arranged in said 1902. pocketand movable vertically in said side 1 openings and slots and capable ofbeing lifted GEORGE LEWIS 5 up within the pocket, and means at oppositeWitnesses:

ends to prevent its escape from said pocket. T. R. JOHNSON, In testimonywhereof I have hereunto set F. W. CLARK.
